Thing is though that the over all performance after digital corrections can be quite good. You can't do it with a dslr because the framing will be off. Still makes me wonder about that supposed mirrorless advantage for lens design due to register distance. So far all I can see is a whole lot of software corrections and that doesn't justify the pricing to me since those same corrections can be applied to vintage glass as well.
Two things about digital corrections. First of all, they reduce the amount you can push a photo after they've been done -- the corners are noisier, maybe by a couple of stops, dynamic range not quite so good. The second thing is that they effectively crop a couple of mm off of an image. Not a big deal in many situations, but particularly on the wide end, can be a problem.
If you are going to be paying a thousand dollars for a 24-70 f4 lens (as the Nikon S is priced), you'd like it to perform a bit better without software manipulation, at least I would.
From a review standpoint, I do think it is important the review sites compare these lenses without any correction so that there is a level playing field. Typically Pentax lenses require clicking a button to get the lens correction on, it sounds as though with the Nikon Z they automatically do it in Lightroom.
